BACKGROUND OF THE INVENTION

1. Technical Field of the Invention

This invention relates generally to communication devices and moreparticularly to the communication devices that communicate with multiplenetworks in multiple frequency bands.

2. Description of Related Art

Wireless communication systems are known to support wirelesscommunications between wireless communication devices affiliated withthe system. Such wireless communication systems range from nationaland/or international cellular telephone systems to point-to-pointin-home wireless networks. Each type of wireless communication system isconstructed, and hence operates, in accordance with one or morestandards. Such wireless communication standards include, but are notlimited to IEEE 802.11, 802.15, 802.16, long term evolution (LTE),Bluetooth, advanced mobile phone services (AMPS), digital AMPS, globalsystem for mobile communications (GSM), code division multiple access(CDMA), wireless application protocols (WAP), local multi-pointdistribution services (LMDS), multi-channel multi-point distributionsystems (MMDS), and/or variations thereof.

An IEEE 802.11 compliant wireless communication system includes aplurality of client devices (e.g., laptops, personal computers, personaldigital assistants, etc., coupled to a station) that communicate over awireless link with one or more access points. As is also generallyunderstood in the art, many wireless communications systems employ acarrier-sense multiple access (CSMA) protocol that allows multiplecommunication devices to share the same radio spectrum. Before awireless communication device transmits, it “listens” to the wirelesslink to determine if the spectrum is in use by another station to avoida potential data collision. In other systems, transmissions can bescheduled using management frames or power save multi-poll (PSMP), forexample. In many cases, the transmitting device (e.g., a client deviceor access point) transmits at a fixed power level regardless of thedistance between the transmitting device and a targeted device (e.g.,station or access point). Typically, the closer the transmitting deviceis to the targeted device, the less error there will be in the receptionof the transmitted signal.

A cognitive radio is a wireless communication device that can adjusttransmission or reception parameters to communicate efficiently toavoiding interference. This alteration of parameters can be based on theactive monitoring of several factors in the external and internal radioenvironment, such as radio frequency spectrum, user behavior and networkstate.

When one or more of these communication devices is mobile, its transmitand receive characteristics can change with the motion of the device, asit moves closer or farther from a device it is communication with, andas the transmission environment changes due to the devices position withrespect to reflecting members, interfering stations, noise sources, etc.

The limitations and disadvantages of conventional and traditionalapproaches will become apparent to one of ordinary skill in the artthrough comparison of such systems with the present invention.

FIG. 5 is a schematic block diagram of an embodiment of RF transceiver123, such as transceiver 73 or 73′, in accordance with the presentinvention. The RF transceiver 123 includes an RF transmitter 129, and anRF receiver 127. The RF receiver 127 includes a RF front end 140, a downconversion module 142 and a receiver baseband processing module 144 thatoperate under the control of control signals 141. The RF transmitter 129includes a transmitter baseband processing module 146, an up conversionmodule 148, and a radio transmitter front-end 150 that also operateunder control of control signals 141.

As shown, the receiver and transmitter are each coupled to an antennathrough an antenna interface 171 and a diplexer (duplexer) 177, such asantenna interface 72 or 74, that couples the transmit signal 155 to theantenna to produce outbound RF signal 170 and couples inbound signal 152to produce received signal 153. Alternatively, a transmit/receive switchcan be used in place of diplexer 177. While a single antenna isrepresented, the receiver and transmitter may share a multiple antennastructure that includes two or more antennas. In another embodiment, thereceiver and transmitter may share a multiple input multiple output(MIMO) antenna structure, diversity antenna structure, phased array orother controllable antenna structure that includes a plurality ofantennas. Each of these antennas may be fixed, programmable, and antennaarray or other antenna configuration.

In operation, the transmitter receives outbound data 162 from otherportions of its a host device, such as a communication applicationexecuted by processing module 225 or other source via the transmitterprocessing module 146. The transmitter processing module 146 processesthe outbound data 162 in accordance with a particular wirelesscommunication standard (e.g., IEEE 802.11, Bluetooth, RFID, GSM, CDMA,et cetera) to produce baseband or low intermediate frequency (IF)transmit (TX) signals 164 that contain outbound data 162. The basebandor low IF TX signals 164 may be digital baseband signals (e.g., have azero IF) or digital low IF signals, where the low IF typically will bein a frequency range of one hundred kilohertz to a few megahertz. Notethat the processing performed by the transmitter processing module 146can include, but is not limited to, scrambling, encoding, puncturing,mapping, modulation, and/or digital baseband to IF conversion.

The up conversion module 148 includes a digital-to-analog conversion(DAC) module, a filtering and/or gain module, and a mixing section. TheDAC module converts the baseband or low IF TX signals 164 from thedigital domain to the analog domain. The filtering and/or gain modulefilters and/or adjusts the gain of the analog signals prior to providingit to the mixing section. The mixing section converts the analogbaseband or low IF signals into up-converted signals 166 based on atransmitter local oscillation.

The radio transmitter front end 150 includes a power amplifier and mayalso include a transmit filter module. The power amplifier amplifies theup-converted signals 166 to produce outbound RF signals 170, which maybe filtered by the transmitter filter module, if included. The antennastructure transmits the outbound RF signals 170 to a targeted devicesuch as a RF tag, base station, an access point and/or another wirelesscommunication device via an antenna interface 171 coupled to an antennathat provides impedance matching and optional bandpass filtration.

The receiver receives inbound RF signals 152 via the antenna andoff-chip antenna interface 171 that operates to process the inbound RFsignal 152 into received signal 153 for the receiver front-end 140. Ingeneral, antenna interface 171 provides impedance matching of antenna tothe RF front-end 140, optional bandpass filtration of the inbound RFsignal 152 and optionally controls the configuration of the antenna inresponse to one or more control signals 141 generated by processingmodule 225.

The down conversion module 142 includes a mixing section, an analog todigital conversion (ADC) module, and may also include a filtering and/orgain module. The mixing section converts the desired RF signal 154 intoa down converted signal 156 that is based on a receiver localoscillation, such as an analog baseband or low IF signal. The ADC moduleconverts the analog baseband or low IF signal into a digital baseband orlow IF signal. The filtering and/or gain module high pass and/or lowpass filters the digital baseband or low IF signal to produce a basebandor low IF signal 156. Note that the ordering of the ADC module andfiltering and/or gain module may be switched, such that the filteringand/or gain module is an analog module.

The receiver processing module 144 processes the baseband or low IFsignal 156 in accordance with a particular wireless communicationstandard (e.g., IEEE 802.11, Bluetooth, RFID, GSM, CDMA, et cetera) toproduce inbound data 160. The processing performed by the receiverprocessing module 144 includes, but is not limited to, digitalintermediate frequency to baseband conversion, demodulation, demapping,depuncturing, decoding, and/or descrambling.

Further, processing module 225 generates one or more control signals 141to configure or adapt the RF transceiver 123 to communication with oneor more of the networks 2, 4, 6 and 8. In operation, processing module225 generates control signals 141 to modify the transmit and/or receiverparameters of the RF transceiver 125 such as protocol parameters, datarates, modulation types and other data parameters used by receiverprocessing module 144 and transmitter processing module 146, frequencybands, channels and bandwidths, filter settings, gains, power levels,ADC and DAC parameters, and other parameters used by RF front-end 140,radio transmitter front-end 150, down conversion module 142 and upconversion module 148, as well as antenna configurations used by antennainterface 171 to set the beam pattern, gain, polarization or otherantenna configuration of the antenna.

The control signals 141 can be analog signals, digital signals,discrete-time signals of other signals that control the modules of RFtransceiver 123 to adapt to communication via different networks. Forexample, in one mode of operation, communication device 125 includes aplurality of different transceivers 73 . . . 73′, that are each designedand implemented by a particular RF transceiver 123 for communicatingwith one of the plurality of networks 2, 4, 6 and/or 8. Each of these RFtransceivers 123 can be selectively enabled or disabled via controlsignals 141 to operate under the control of processing module 225 tocommunicate with its corresponding network 2, 4, 6 or 8 when required.In another embodiment of the present invention one or more of thetransceivers 73 . . . 73′ is implemented via a cognitive radiotransceiver or other flexible RF transceiver 123 that can be configuredto communicate with different networks based on a selected mode ofoperation. For example, such a flexible RF transceiver 123 can beconfigured to operate as either a Bluetooth transceiver, a GSMtransceiver or a 802.11g transceiver based on the generation of thecontrol signals 141 to implement the corresponding transmit and receivecharacteristics. Further details regarding particular conditions forgenerating control signals 141 will be discussed in conjunction withFIGS. 6-51 that follow.

FIG. 6 is a schematic block diagram of another embodiment of acommunication device 125 in accordance with the present invention. Inparticular, a communication device is shown that includes many commonelements shown in conjunction with FIG. 4. In this embodiment however,IC 50 includes an optional receiver 77, such as an environmentalmonitoring receiver, that can evaluate the RF environment via ananalysis of RF signal spectrum 203.

In particular, communication device 125 includes a plurality oftransceivers 73 that wirelessly transceive data with a correspondingplurality of networks, such as networks 2, 4, 6, 8, etc. in accordancewith a corresponding plurality of network protocols. Receiver 77receives and processes received RF signals, over a broadband spectrum,such as RF signal spectrum 203 and generates environmental data inresponse thereto. Processing module 225 processes the environmental dataand generates one or more control signals 141 in response thereto foradapting the transceivers 73 based on the environmental data.

In operation, receiver 77 analyzed an RF spectrum that encompasses thefrequency bands used by each of the transceivers 73 including optionalfrequency bands that can be used by each of these transceivers. Theenvironmental data can identify unused spectrum, used spectrum, desiredchannels, undesired channels, noise and interference, that can be usedto adapt the transceivers 73 to more favorable conditions.

In one example, when conditions with respect to a particular frequencychannel begin to deteriorate or otherwise a better frequency channel isfound by receiver 77 for use by one of the plurality of transceivers 73,processing module 225 can generate control signals 141 and outbound datato coordinate with a remote station via control signaling and to switchthe new frequency channel and to change the transceiver 73 to the newfrequency channel. In another example, when communications with aparticular network begin to deteriorate or otherwise a better network isfound by receiver 77 for use by communication device 125, processingmodule 225 can generate control signals 141 and outbound data tocoordinate a handoff to a new network or a new network device and eitheradapt a transceiver 73 to the new network or switch the transceiver 73in use to a transceiver adapted for communication with the new networkor network device. In addition, transceiver 73 can take on the functionof receiver 77 during idle periods. In a further example, whencommunication conditions, such as noise and interference change for aparticular transceiver, processing module 225 can generate controlsignals 141 to modify a transmission parameter and/or a receiveparameter of the transceiver 73 to adapt to the change in conditions.

In particular, spectrum 210represents an example of an RF signal spectrum 203 received by anenvironmental monitoring receiver, such as receiver 77. In an embodimentof the present invention, the receiver 77 receives and analyses the RFsignal spectrum and can identify unused portions of spectrum, such asavailable spectrum 212, based on the lack of signal energy in thesespectra. In addition, receiver 77 can identify undesired channels, byidentifying regions with unacceptable levels of noise and interference214 based on signal to noise ratios, signal to noise and interferenceratios, packet error rates, data rates, etc.

FIG. 18 is a schematic block diagram of an embodiment of an RFtransceiver 123″ in accordance with the present invention. Inparticular, an RF transceiver 123″ is shown that shares many commonelements of the RF transceivers 123 and 123′ described in conjunctionwith FIGS. 5 and 15 that are referred to by common reference numeralsand that can be used to implement transceivers 73, 73′ and 75. The RFtransceiver 123″ includes an RF transmitter 229, and an RF receiver 227.The RF receiver 227 includes a RF front end 140, a down conversionmodule 142 and a receiver processing module 144′. The RF transmitter 229includes a transmitter processing module 146′, an up conversion module148, and a radio transmitter front-end 150.

As shown, the receiver and transmitter are each coupled to an antennathrough an antenna interface 171 and a diplexer (duplexer) 177, such asantenna interface 72 or 74, that couples the transmit signal 155 to theantenna to produce outbound RF signal 170 and couples inbound signal 152to produce received signal 153. Alternatively, a transmit/receive switchcan be used in place of diplexer 177. While a single antenna isrepresented, the receiver and transmitter may share a multiple antennastructure that includes two or more antennas. In another embodiment, thereceiver and transmitter may share a multiple input multiple output(MIMO) antenna structure, diversity antenna structure, phased array orother controllable antenna structure that includes a plurality ofantennas. Each of these antennas may be fixed, programmable, and antennaarray or other antenna configuration.

In operation, the transmitter receives outbound realtime data 162 fromother portions of its a host device, such as a communication applicationexecuted by processing module 225 or other source via the transmitterprocessing module 146′. The transmitter processing module 146′ processesthe outbound data 162 in accordance with a particular wirelesscommunication standard (e.g., IEEE 802.11, Bluetooth, RFID, GSM, CDMA,et cetera) to produce baseband or low intermediate frequency (IF)transmit (TX) signals 164 that contain outbound data 162. The basebandor low IF TX signals 164 may be digital baseband signals (e.g., have azero IF) or digital low IF signals, where the low IF typically will bein a frequency range of one hundred kilohertz to a few megahertz. Notethat the processing performed by the transmitter processing module 146′can include, but is not limited to, scrambling, encoding, puncturing,mapping, modulation, and/or digital baseband to IF conversion.

The up conversion module 148 includes a digital-to-analog conversion(DAC) module, a filtering and/or gain module, and a mixing section. TheDAC module converts the baseband or low IF TX signals 164 from thedigital domain to the analog domain. The filtering and/or gain modulefilters and/or adjusts the gain of the analog signals prior to providingit to the mixing section. The mixing section converts the analogbaseband or low IF signals into up-converted signals 166 based on atransmitter local oscillation.

The radio transmitter front end 150 includes a power amplifier and mayalso include a transmit filter module. The power amplifier amplifies theup-converted signals 166 to produce outbound RF signals 170, which maybe filtered by the transmitter filter module, if included. The antennastructure transmits the outbound RF signals 170 to a targeted devicesuch as a RF tag, base station, an access point and/or another wirelesscommunication device via an antenna interface 171 coupled to an antennathat provides impedance matching and optional bandpass filtration.

The receiver receives inbound RF signals 152 via the antenna andoff-chip antenna interface 171 that operates to process the inbound RFsignal 152 into received signal 153 for the receiver front-end 140. Ingeneral, antenna interface 171 provides impedance matching of antenna tothe RF front-end 140, optional bandpass filtration of the inbound RFsignal 152 and optionally controls the configuration of the antenna inresponse to one or more control signals 141 generated by processingmodule 225.

The down conversion module 142 includes a mixing section, an analog todigital conversion (ADC) module, and may also include a filtering and/orgain module. The mixing section converts the desired RF signal 154 intoa down converted signal 156 that is based on a receiver localoscillation, such as an analog baseband or low IF signal. The ADC moduleconverts the analog baseband or low IF signal into a digital baseband orlow IF signal. The filtering and/or gain module high pass and/or lowpass filters the digital baseband or low IF signal to produce a basebandor low IF signal 156. Note that the ordering of the ADC module andfiltering and/or gain module may be switched, such that the filteringand/or gain module is an analog module.

The receiver processing module 144′ processes the baseband or low IFsignal 156 in accordance with a particular wireless communicationstandard (e.g., IEEE 802.11, Bluetooth, RFID, GSM, CDMA, et cetera) toproduce inbound data 160. The processing performed by the receiverprocessing module 144′ includes, but is not limited to, digitalintermediate frequency to baseband conversion, demodulation, demapping,depuncturing, decoding, and/or descrambling.

In an embodiment of the present invention, the RF transceiver 123″ canbe configured as a control channel transceiver to receive inbound data160 that includes cognitive transceiver configuration data 260. The RFtransceiver 123″ can be configured as a control channel transceiver in adefault mode of operation and then reconfigure itself based on thecognitive transceiver configuration data 260 received via either aphysical or logical control channel established with management unit 200or 201. Then, for example, when communication device 125 completes thetask assigned to it in its reconfigured state, the RF transceiver 123″can reconfigure itself again to revert back to operation as a controlchannel transceiver.

The processing module 225 receives the cognitive transceiverconfiguration data 260 and generates one or more control signals 141 toconfigure or adapt the RF transceiver 123″ in response thereto. Like theprocessing module 225 of RF transceiver 123′, processing module 225generates control signals 141 to modify the transmit and/or receiverparameters of the RF transceiver 125 such as protocol parameters, datarates, modulation types and other data parameters used by receiverprocessing module 144′ and transmitter processing module 146′, frequencybands, channels and bandwidths, filter settings, gains, power levels,ADC and DAC parameters, and other parameters used by RF front-end 140,radio transmitter front-end 150, down conversion module 142 and upconversion module 148, as well as antenna configurations used by antennainterface 171 to set the beam pattern, gain, polarization, frequencyband or other antenna configuration of the antenna.

For example, the cognitive transceiver configuration data 260 caninclude receiver frequency band configuration data for configuring thefrequency band of the receiver front-end 140 via adjustment of a localoscillator frequency, filter bandwidth, etc, via control signals 140.The cognitive transceiver configuration data 260 can include transmitterfrequency band configuration data for configuring the frequency band ofthe transmitter front end via adjustment of a local oscillatorfrequency, filter bandwidth, etc. The cognitive transceiverconfiguration data 260 can include baseband processing configurationdata for configuring at least one baseband processing parameter of thereceiver baseband processing module 144′ such as a particular modulationscheme, protocol, data rate, etc. The cognitive transceiverconfiguration data 260 can include baseband processing configurationdata for configuring at least one baseband processing parameter of thetransmitter baseband processing module 146′ such as a particularmodulation scheme, protocol, data rate, etc.

The control signals 141 can be analog signals, digital signals,discrete-time signals of other signals that control the modules of RFtransceiver 123″ to adapt to communication via different networks. Inthis fashion, such a cognitive RF transceiver 123″ can be configured tooperate as either a Bluetooth transceiver, a GSM transceiver or a802.11g transceiver based on the generation of the control signals 141to implement the corresponding transmit and receive characteristics.

In a further mode of operation, the receiver processing module 144′includes a receiver application memory 240 that stores a receiverapplication that is executed by the receiver processing module toperform the functionality of this receiver processing module 144′. In adefault mode of operation the receiver application memory can store adefault receiver application that causes the receiver processing moduleto operate in a particular configuration—such as a GSM receiver, aBluetooth receiver, a CDMA receiver, a WIMAX receiver, and UWB receiver,a 802.11 receiver or as a control channel receiver, etc. The cognitivetransceiver configuration data 260 can includes other basebandprocessing application data that can be received and stored in receiverapplication memory 240 and for execution by the receiver basebandprocessing module 144′ in a new configuration. For example, whileoperating as a control channel receiver, the RF receiver 227 can receivecognitive transceiver configuration data 260 that includes basebandprocessing application data with a new receiver application, for examplea GSM receiver application, that is stored in receiver applicationmemory 240 and executed by the receiver baseband processing module 144′as part of a reconfiguration of the RF receiver 227 by processing module225 as a GSM receiver.

In a similar fashion, the transmitter processing module 146′ includes atransmitter application memory 241 that stores a transmitter applicationthat is executed by the transmitter processing module to perform thefunctionality of the transmitter processing module 146′. In a defaultmode of operation, the transmitter application memory can store adefault transmitter application that causes the transmitter processingmodule to operate in a particular configuration—such as a GSMtransmitter, a Bluetooth transmitter, a CDMA transmitter, a WIMAXtransmitter, and UWB transmitter, a 802.11 transmitter or as a controlchannel transmitter, etc. The cognitive transceiver configuration data260 can includes other baseband processing application data that can bereceived and stored in transmitter application memory 241 and forexecution by the transmitter baseband processing module 146′ in a newconfiguration. For example, while operating as a control channeltransceiver, the RF transceiver 123″ can receive cognitive transceiverconfiguration data 260 that includes baseband processing applicationdata with a new transmitter application, for example a GSM transmitterapplication, that is stored in transmitter application memory 241 andexecuted by the transmitter baseband processing module 146′ as part of areconfiguration of the RF transmitter 229 by processing module 225 as aGSM transmitter.
